Arenaria montana 'Summer White Compact' is a low-growing, mat-forming perennial that offers a blanket of pure white, star-shaped flowers throughout the summer. The small, evergreen foliage provides a dense, carpet-like effect, making it an ideal groundcover or filler for rock gardens, borders, or container plantings. This compact variety thrives in full sun and well-drained soil, tolerating dry conditions once established. Its delicate blooms and tidy growth habit add a soft, bright touch to the landscape, while attracting pollinators with its abundant flowers.
